HYDRAULIC on. sronaen AND msrninurron SYSTEM nnvme a nn'norn eonrnon y t I Application filed February 9, 1922. Serial No. 535,424.

p v v The invention relates to hydraulic oil storage and distribution systems and is particularlydesigned for use in buildings'w ere the oil is distr'buted to various points more or 5 less remote f 10111 the point of. storage. It is the object ofthe invention to provide con-- 'trolling means by which the system may be operated from any one of the various points- 'of delivery and without interference with the simultaneous delivery to other points. To this end the invention consistsrin the construction as hereinafter set forth. 1

- In the drawings: t

Figure 1 isa diagrammatic view. showing the systemand the electric controlling means therefor;

FigureQ is anelevation of the draw-off valve.

A is a stora e tank suitably located and preferably buried in the ground. "B is a conduit for the displacement liquid, which is supplied with waterunder the desired 7 head from an elevated tank C having a float valve D ton controlling the supply thereto.

E ,is the oil delivery conduit providedwith v a riser portion E extending to above the level of the water head and then-returning to a lowerlevel, as, for instance, beneath the floor of the building and extending laterally to various points of consumption. A. siphon breaker F is placed' in the rgturn-bend of the conduit E and thus the forcing of water beyond-the riser-E" is efiectuall prevented. The lateral portionQE of the d e duit E is extended as far as desired and any number of draw-ofi connections may. be attached thereto. As shown, G, G, etc., are different draw-01f connections rising from the conduit E and each provided with a dispensing or oiLdraw-oflf valve H. They .To deliver oil at .any one of the dra w-ofi" points, it is necessary to control the supply,

' of displacement fluid which enters the stora e tank A through-the conduit B. For

,t is purpose a valve K is placed in the fluid 0 displacement pipe or conduit Bfor opening or cutting off connection with the float box Q.-. and this-Ivalve K is electrically operated as 'by means of a solenoid LC The electrlc circuit M controlling the solenoid extends to each ofthe delive Npoints and a normally -:open 'eleetrie syvitch is connected in multilivery con may be further provided with a meter I for p1e into this circuit. A normally open switch N is-assooiated with oi; mounted on each normally closed draw-01f valve H and. suitable connection is .p'referablymade, so. that the opening of the normally-i closed draw-off valve. H will simultaneously effect the closing Jo'f theswitch; Thus. whenever one of the 011 dispensingvalves His manu:

ally opened, that operation closes the elec- 05 trio circuit which energizes the solenoid L, which, by. opening .the displacement fluid' valve K, will permit the water 'head'of the float box G' to become effective upon the J tank .A. This will displace the oil fr'om 7 said tank and propel it to the delivery point, the flowcontinuing until the valve H is closed, whereupon the switch N is auto matically opened by releasing the handle of the valve H and the solenoid L is de-ener- 7 igized permitting the closing of the valve Should it occur that several of the valves are opened at the same time, oil will-be delivered to each of thedelivery points and the closing of one :valve willnot fefi'ect the delivery of -oil to another one. Thusthe flow, will continue until the last'valve'H is I closed, after which the valve K will be closed and the pressure of the water'hea'd removed from the tank A. i. F

When the valve K is closed, the .water re-' mains in the conduit B up tothe valve but does not exert a hydrostatic pressure. If for any reason it is desired to drain ofl' this? water,, a-drain valve .0 maybe opened by a pull connection P. If desired,- the electrical operating connec'tionsmay all be controlled by a master switch Q, which, when open, will out oflf. current from the system.

Also. automatie cut-out switches, asindi- 95.

valve H is automatically closed by a spring 105 S when the operator releases the valve han-' dle so that the valve H remains normally closed. The spring S also constitutes automatic opening means for the switchN'since the switch N is caused to quickly open and break thecircuit M when. the operator re. leases the handle of the valve H so that the is normally closed.

1. Oil dispensing system comprising in a combination, an oil storage tank, a pipe con:

necting therewith through which a displacement fluid flows into the tank to propel oil from the tank, a valveincluded in the pipe, electrically-operating means to open and close the valve to stop and start the flow of displacement fluid to said tank, [an oil delivery line connecting with the tank, an oil.

dispensing draw-oft" valve included in the delivery linc, a switch operatively. connected. with the oily dispensing draw-off valve, and -an electrical circuit connection established between the switch and atoresaid electrically operating means.

2. Q1l,dispens1ng system comprising in combination, an oil storage tank, a pipe connecting therewith through which a displacement fluid flows into-the tank to propel oil from the tank, a valveincluded in the pipe,

, combination, an oil storage tank, a fluid pipe electrically operating means to open and] i close the valve to stop and start the flow of displacement fluid to said tank, a plurality of -oil delivery lines connected with, the tank, an oil draw-off valve included in each oildelivery line. an electric switch, operatively connected with each oil draw-ofl valve, and a circuit wire connection estab lished between the electrically operatingmeans and the several switches.

3. An oil dispensing system as defined in claim 1 but characterized by a safety cutout switch included in the electr1c c1rcuit included in the fluid pipe, a solenoid coopcrating with the fluidvalve to open and 'close it, an oil delivery line leading from gvalve, a switch mounted on the d spensing the oil'storage tank, a normally closed draw-' off valve in the oil delivery line tlnough. which-oilis dispensed, a handle on the drawofl. valve by which it is manually opened I from its normally closed position, valve closing means cooperating with the draw-oflf valve vvhich automatically closes it hen the handle is released, a normally ope switch operatively connected with thenormallyc1osed'draw-ofl valve, a switch operating means actuated by the draw-off valve to and a circuit-wire connected between the solenoid and the switch by which the nor mally closed "fluid valve is automatically opened when the draw-ofi' valve is manually opened and by which said fluid valve is automatically closed when the draw-off valve is closed.
